Castle of Black Iron

"Tang Mei, Tang Mei, what an unrivaled talented beauty... she deserves to be Bian Sage's disciple; she deserves to be Bian Sage's Disciple..."

A youth stumbled out of a boite with a flagon in hand and brushed past Zhang Tie. At the same time, he kept drinking. Pitifully, soon after stumbling a few steps forward, he had stopped at a roadside parterre and started to vomit. As a result, the air was stinky at a stroke...

Watching this youth, Zhang Tie slightly frowned as he hastened his pace.

Zhang Tie had just come out of Du's Fish Store where he guided Boss Du for the entire afternoon and negotiated with some fear-stricken spike shrimp fishermen about buying some fishing boats for setting free spike shrimps. After a few hours' busy work, Zhang Tie finally became reassured.

Bian Heng had already selected his disciple in the morning. At noon, Zhang Tie had already returned to Du's Fish Store in Tigerback Town and urged Boss Du to start it.

The fruits of redemption from spike shrimps were of great significance to Zhang Tie. Zhang Tie would have no grumble even if he went to Du's Fish Store for 20 times or 200 times, not to mention 2 times. Thankfully, after this trip, Zhang Tie had almost arranged everything properly. He didn't need to concern more about it. Even though Boss Du was in trouble, Zhang Tie still didn't worry about that as he had already prepared plan B. All in all, spike shrimps could be set free constantly.

Today, Tigerback Town was even more lively than before. When lamps were lit, those boites became even more boisterous than before. All the boites in Tigerback Town were filled with people. Drunk people could be seen everywhere across the streets. The name of Tang Mei could be heard everywhere.

Due to grief and disappointment, those doctors, who would never have an opportunity to go up Tigerback Mountain, drank as much as possible with their friends in boites.

In only one day, the name of Tang Mei had spread over Tigerback Town, together with her beautiful look and talent.

Previously Zhang Tie wanted to have supper in a boite before going back to Tigerback Mountain. However, watching the boisterous situation facing those boites, Zhang Tie shook his head slightly as he gave it up.

It was okay for him to not eat food for a day.

Strolling on the streets of Tigerback Town and watching Tigerback Mountain which was brightly lit in the distance, Zhang Tie stroked his nose, 'I'm afraid that Bian Heng has already known that it was me who helped Tang Mei.'

Although Tang Mei was smart, she still couldn't pass the last test only with her intelligence; instead, it required a superb mathematical computing ability.

Soon after going back to Tigerback Mountain, Bian Heng might have known that it was Zhang Tie who helped Tang Mei in the end. Tang Mei couldn't cheat Bian Heng at all; nor would she cheat him given her intelligence.

When he imagined Bian Heng's dumbfounded look after knowing the truth, Zhang Tie couldn't help revealing a cunning smile.

'No matter what, you have to cure your disciple's cancer. If Tang Mei died, this No. 1 doctor in Motian Realm would feel disgraced.'

...

When Zhang Tie returned to the foot of Tigerback Mountain, he noticed that General Butler Qin was waiting for him over there.

"Butler Jin, owner asked me to wait for you here and take you to him when you come back!" General Butler Qin said calmly as he took a deep look at Zhang Tie.

"Sorry for being late, let go..."

Previously, Zhang Tie thought that General Butler Qin would wait for him in Tideviewing Courtyard; unexpectedly he was waiting for him at the foot of Tigerback Mountain. It seemed that Bian Heng was already anxious. If Zhang Tie was a bit late, Bian Heng might have gone to Tigerback Town and brought him back.

...

In the same parlor where Zhang Tie met Bian Heng for the first time, when Zhang Tie strode over the threshold, Bian Heng who was walking around in the parlor with his hands clasped behind his back had rushed forward with a furious look, "Was that you?"

Zhang Tie blinked his eyes as he shrugged with an innocent look, saying, "Elder brother, what are you talking about? I don't understand..."

"You're still pretending to be innocent?" Bian Heng roared as he almost sprayed his saliva on Zhang Tie's face, "Tang Mei has admitted that someone told her the answer of the last question. Is she the very person suffering from cancer that you wanted me to cure? Even a fool could figure it out..."

"Did Tang Mei say that it was me who told her the answer of the third question?" Zhang Tie asked calmly without any fear.

Bian Heng became shortly stunned as he answered, "Not yet. She said that she couldn't identify the owner of the voice..."

"That's it..." Zhang Tie walked to the front of a chair and sat down frankly. Closely after that, he picked a piece of pastry from the teapoy and put it in his mouth. As he ate it, he urged, "Even she couldn't confirm that it was me, how could you confirm that? You should find evidence for that. Perhaps a powerhouse couldn't stand Tang Mei from being killed by cancer; therefore, he warned her. Everyone likes beauty..."

Bian Heng's face almost twisted out of fury as he blew his beard and roared, "Powerhouse, sh*t! Nobody could play this trick in front of me except immortal emperors or demon emperors. At that time, at the foot of the mountain, you were the most powerful one after me. I've already seen through you. You've long known that she was beautiful; therefore, you had a crush on her. Then, you took advantage of me, right?"

"It's just your presumption..." Zhang Tie said seriously as he continued to pick the pastries from the teapoy.

Sitting beside Zhang Tie with fury, Bian Heng reached out his hand and drew the tray of pastries to his own side so that Zhang Tie couldn't get it, roaring, "You've cheated me, how dare you still take my food..."

"Come on, I've not had supper yet!" Zhang Tie smiled shamelessly as he picked himself up, bending over and grasping all the remaining pastries in the tray. As he ate food, he said, "If you stick to that I've cheated you, I would never admit that. But I was born to be smart and adorable. I'm proficient in... mathematics. Elder brother, if you help me cure her, I owe you. If you have any questions about mathematics, you could seek my help. I would never refuse it... Oh, by the way, elder brother, the third question was called magic square in the world where I came from. I'm always good at filling magic square..."

Apparently, Zhang Tie had already admitted that it was him who did it. Of course, Bian Heng understood it.

Therefore, Bian Heng looked a bit better.

"Mathematics... magic square..." Bian Heng mumbled as he peeped at Zhang Tie, saying, "Now that you're proficient in mathematics, I've got a question..."

"Go ahead..."

"What's 387 multiplied by 987 multiplied by 247 divided by 3?"

"31,448,781..." Zhang Tie instantly answered with food in mouth.

Bian Heng was shortly stunned. Actually even Bian Heng didn't know the answer. Despite being a supreme-level immortal general, he was also not almighty. He just wanted to mock Zhang Tie and test his mathematics computing ability; however, Zhang Tie answered him in the blink of an eye. Therefore, Bian Heng became shortly stunned.

He thought that Zhang Tie was fabricating it; how could the product of three 3-digit numbers being divided by 3 be completely divisible? However, given Zhang Tie's calm and leisure look, Bian Heng wavered his mind as he poured out some tea water and started to calculate by finger on the teapoy.

One minute later, Bian Heng raised his head as he watched Zhang Tie with an astonished look. The answer to the question was indeed 31,448,781. He got the same answer after computing it twice.

"Do you believe in me?" Zhang Tie asked Bian Heng after gulping down the pastries and cleaning his mouth.

Watching the bizarre light in Zhang Tie's eyes, Bian Heng asked, "How long did it take you to work out the answer of the third question in the morning..."

"Within one second..."

"What about something more complex?"

"It depends, approximately 1 or 2 seconds..."

After hearing Zhang Tie's words, Bian Heng looked at Zhang Tie with greater curiosity, "Does everyone in your world have such an amazing calculating ability like you?"

"No, few of them could match me in calculating ability..." Zhang Tie replied with a smirk.

Bian Heng suddenly became silent as his expression started to change, pleasant or sad. Zhang Tie wondered what he was thinking about.

"Anything else? If no, I gotta get going..." Zhang Tie said as he stood up.

When Zhang Tie walked to the gate of the parlor, Bian Heng suddenly opened his mouth, "Do you want to make a fortune?"

"Make a fortune? Forget about it. In our stage, ordinary element crystals don't work anymore. I'm not even interested in common immortal outfits..." Zhang Tie stopped as he turned around and answered.

"I'm not interested in ordinary immortal outfits either; but what about immortal's secret method and heavenly-level immortal outfits?"

"Immortal's secret method?" Zhang Tie thought it for a second as he realized that immortal's secret method in Motian Realm were actually emperor-level classics. Therefore, his heart palpitated once. However, he said with a dubious look, "There are very few immortal's secret methods. Elder brother, you must be cheating me."

"Have you heard about Infinite King Roc Sutra?" Bian Heng watched Zhang Tie with gleaming eyes.

'F*ck! Infinite King Roc Sutra?'' Zhang Tie was spirited at a stroke like being hit by a lightning bolt.

"Where's the Infinite King Roc Sutra?" Zhang Tie instantly asked as his eyes gave out bright light. As a cultivator, it was impossible for him to not be interested in an emperor-level secret method. A eunuch might not be interested in beauty, but the road and secret method that could lead to a supreme realm were irresistible to a cultivator.

"I know where it is, but I can't tell you about that..." Bian Heng said as he shook his head.

"Whatever..." Zhang Tie continued to walk outward.

"But if you want to know it, you could go to a place together with me. As long as you could prove your ability, you might get the opportunity to know its whereabouts..."

"What do you mean?"

Bian Heng watched Zhang Tie seriously as he said, "As this secret doesn't belong to me alone, I don't have the right to expose it to you. If you want to know it, you must join us. With the consent of all the others who know this secret, you will be able to know it..."
